Question

Do humans have chloroplast?

Answer 1

Hint: Chloroplast is a cell organelle that is involved in the process of photosynthesis and is involved in the conversion of light energy to energy which is stored in the form of organic molecules. It is a plastid that contains chlorophyll.

Complete answer:
Chloroplasts are present in the plant cell and it is not present in humans. It contains a pigment known as chlorophyll which captures the energy from the sunlight and helps in the conversion of the energy and stores it in the energy storage molecule known as ATP and NADPH. They are used to make the organic molecules from the carbon dioxide which involves a process known as the Calvin cycle. It helps in the synthesis of fatty acids and amino acids. They respond to the immune responses in the plant. It is an organelle that is a plastid and is composed of two membranes that have a high concentration of chlorophyll.
The guard cells of the plant consist of a well-developed chloroplast. The chloroplast which contains the endoplasmic reticulum, cell membrane and nucleus is vital in playing the pathogen defence mechanism. The chloroplast helps in stimulating the hypersensitive response and the systemic acquired resistance by damaging the photosynthetic system and producing oxygen reactive species. They act as cellular sensors and detect the stress in the cell which is due to the pathogen and the molecules like salicylic acid and other reactive oxygen species act as the defence signals.
So the correct answer is no humans do not have chloroplasts, as this is the cell organelle present in organisms responsible for performing photosynthesis.

Note:
A chloroplast is found in certain algae and is used to capture radiant energy from the sunlight. The chloroplast is present in the chlorenchyma cell of the plant cell. Terrestrial plants are composed of chloroplasts that are lens-shaped.
